- India’s coastline had increased from 7,516.6 km to 11,098.8 km, and that the length is also currently under review by the Home Ministry.
- The 7,516.6 km figure was first recorded in the 1970s based on measurement techniques available at the time.
- India has 11 coastal States and two large island groups.
- The last coastal State to join the Union of India was Goa in 1961 and the only other State that joined after — Sikkim in 1975 — is landlocked.
- The previous estimate from the 1970s banked on maps that displayed India’s coastline at a 1:4,500,000 resolution.
- The more recent updated measurement was performed by National Hydrographic Office (NHO) and the Survey of India.
- It used electronic navigation charts at a much finer scale of 1:250,000.
